Vitamin B3 (Niacin) helps the body utilize proteins, fats and carbohydrates for energy, and also supports nerve and skin health. Niacin may help the body’s efforts to lower cholesterol. Niacin assists in the functioning of the digestive system, skin, and nerves.*

The eight vitamins that make up the B complex are water soluble, meaning the body does not store excess amounts, with the exception of vitamin B12, which is stored in the liver. Rather, unused B vitamins are excreted through urine. This means you need a continuous supply of the B vitamins from the diet.


Ingredients
Vitamin B3 (niacin as nicotinic acid), rice flour, gelatin (bovine) capsule

Suggested Use
Adults and children 12 and over, take 1 capsule daily with a meal or as directed by a health professional.

Note: Niacin may cause a hot flush, characterized by a reddening and warming of the skin. This is not dangerous and will pass.

Store at room temperature. Keep out of reach of children.


Frequently Asked Questions
Q: What is the capsule size?

Why Choose Us? With over three decades of unparalleled experience in the health and wellness industry, Dr. Clark Store stands out as a beacon of trust and quality. Unlike others, we are the actual manufacturers who take pride in our craft, overseeing the entire production process to ensure that each bottle meets our high standards. With more than 31 years of expertise and over 10 million bottles produced, you can rest assured that you're choosing a partner dedicated to authentic wellness. We don’t outsource to the lowest bidder.

Guaranteed Authenticity: Every batch of Vitamin B3 is carefully sourced and undergoes rigorous testing for ID, purity, potency, and microbiology before, during, and after manufacturing.

Just Pure Ingredients: At Dr. Clark Store, we stand against adulteration. Our rigorous testing reveals that an estimated 30% of bulk supplement powders in the U.S. market contain added fillers and/or come from incorrect species or plant parts. Unlike importers who operate according to FDA 21 CFR 117 and often rely on analyses done by the manufacturer abroad, we conduct thorough tests on all incoming materials in our full-size laboratory, guaranteeing the integrity of our products.

Carrageenan and Surfactant-Free Capsules: FDA regulation 21 CFR 101.100(a)(3)(ii) allows manufacturers to avoid disclosing ingredients in food if present at “insignificant” levels. This is why "Veggie Capsules" may contain carrageenan. Dr. Clark Store ensures the use of only the finest BSE-free gelatin capsules, free from carrageenan, surfactants, and prion risks. Our dedication to purity dates back over 30 years, ensuring safety and quality in line with Dr. Hulda Clark's original vision.

No Magnesium Stearate and No Hidden Processing Aids: True to Dr. Clark's vision, we never use magnesium stearate or any toxic processing aids in our products. Our commitment to transparency means all ingredients are clearly declared on the label, offering you peace of mind and a product you can trust. Again because of FDA’s lacking regulation 21 CFR 101, many brands contain magnesium stearate without it being declared on the label.

Verifiable GMP Certification: Trust is earned, not given. That's why we back up our GMP certification claims with verifiable evidence. Partnering with VeriGMP®, a UL-certified company, we adhere to strict GMP quality systems, ensuring that each product meets the highest standards of manufacturing and quality assurance.

Choose Dr. Clark Store for your vitamin supplement needs and experience the purity and authenticity that only comes from a legacy of passion and excellence in natural wellness.

What is Vitamin B3 (Niacin)?

Vitamin B3, also known as Niacin, is a vital nutrient that helps maintain good health. One capsule contains 25 mg of this essential vitamin, which plays a prominent role in energy metabolism. It supports the conversion of carbohydrates, fats, and proteins into energy, ensuring that your body can efficiently use the nutrients you consume. Vitamin B3 is essential in the formation of DNA and other critical cellular processes because it helps maintain healthy skin and promotes a healthy nervous system.

The Health Benefits of Vitamin B3

Vitamin B3 offers numerous health benefits, especially for cardiovascular health. It helps improve cholesterol levels by increasing the good HDL cholesterol while lowering the bad LDL cholesterol. This balance can lead to a reduced risk of heart disease. Additionally, Niacin contributes to improved blood circulation, making it easier for nutrients to reach various parts of your body. With these benefits, incorporating Vitamin B3 into your daily routine can lead to better overall health and vitality.

Terrific! Much easier to use than Kongs and my dog loves it.
Flavor Name: Peanut Butter, Size: Medium
I like these so much better than the original Kongs. The large opening makes it so much easier to put peanut butter or cream cheese into it. Plus much easier to clean out afterwards. My dog also likes to chew it and play with it throwing it in the air after he’s done eating the peanut butter. Very sturdy - he chews apart stuffed toys but his chewing hasn’t damaged this at all. I highly recommend this product!

Great for strong chewing dogs. Entertaining too!
Flavor Name: Peanut Butter, Size: Medium
My black lab can destroy the toughest of dog chew toys, but he's not destroyed this peanut. I fill it with peanut butter, yogurt, pumpkin or apple sauce and freeze it. It keeps him entertained for quite a while. When the filling is gone, he leaves it alone or carries it around begging for a filled one.

Super cute! If you have one dog it'll last a while. If you have more than one...buy two.
Flavor Name: Marshmallow & Peanut Butter, Size: Large
This is THE FAVORITE chew toy in our household. We have two grown labs and a 10 month old mutt and they all love this toy. They got a variety of chew toys at Christmas and this is the one that they steal from each other. That said, they've definitely managed to kill it. It's well worth the money and it's held up well to heavy chewers but four months later and we're going to have to buy a new one. It's now a stub. They managed to break off all the marshmallows about a week ago and the stick itself is more like a chunk now but we definitely got our money's worth.

Lasting 6 months in! Great smell.
Flavor Name: Marshmallow & Peanut Butter, Size: Large
This actually does smell like marshmallows which is definitely more pleasant than most dog chews!! It has held up to our power chewer. It’s a bit heavy for our smaller dog but he manages and it’s quite funny!! It’s a bit hard but that’s why it is holding up. Would buy again if this one ever wears out.

Great product
Flavor Name: Peanut Butter, Size: Medium
I have a very active, medium sized dog (heeler). I wish this product was just a little bigger but it is still a great product. I fill it with pureed meat baby food and freeze. A 2.5oz jar will fill this product about 2 times. This keeps my dog busy for a while. Its also great when she's outside on a hot day. I absolutely recommend this product and at such a great price ($6 when I purchased it) i may buy a few more so I'll always have a frozen one ready when needed.
